An alternating emf source with a variable frequency fd is connected in series with a 50.0 ? resistor and a 20.3 ?F capacitor. The emf amplitude is 13.7 V. Consider a phasor diagram for phasor VR (the potential across the resistor) and phasor VC (the potential across the capacitor).

(a) At what driving frequency fd do the two phasors have the same length? At that driving frequency, what are

(b) the phase angle in degrees,

(d) the current amplitude?
